Fire-Fighting Measures

Suitable Extinguishing Media: Use dry chemical, foam, carbon dioxide, or water spray for big fires
Hazards: Nickel oxides, sulfur oxides may form if involved in a fire
Protective Equipment: Firefighters need self-contained breathing apparatus and chemical-resistant gear
Special Procedures: Cool containers exposed to fire with water, avoid inhalation of smoke and combustion products

Accidental Release Measures

Personal Precautions: Evacuate area if dust formation is significant, ventilate, wear protective gloves, goggles, clothing, and an appropriate respirator
Environmental Precautions: Prevent spill from entering sewers or waterways, notify authorities if large releases threaten local environment
Methods for Cleanup: Avoid raising dust, sweep or shovel up into sealed containers, store for proper disposal, wash spill area thoroughly with water

Handling and Storage

Precautions for Safe Handling: Do not eat, drink, or smoke in work area, minimize contact with skin and eyes, avoid generating dust, use appropriate local exhaust ventilation
Conditions for Safe Storage: Store in tightly closed, properly labeled containers in a cool, dry, well-ventilated place, keep away from incompatible materials such as strong acids and reducing agents
Incompatibilities: Strong acids, reactive metals, reducing agents

Exposure Controls and Personal Protection

Occupational Exposure Limits: Nickel compounds: OSHA PEL 1 mg/m³ (as Ni), ACGIH TLV 0.1 mg/m³ (inhalable fraction, as Ni)
Engineering Controls: Work in well-ventilated areas, use local fume extraction at dust-generating sources
Personal Protective Equipment: Safety glasses or goggles, chemical-resistant gloves (nitrile, butyl rubber), long-sleeved protective clothing, respiratory protection (NIOSH-approved P100 or equivalent) if airborne dust is present
Hygiene Measures: Wash hands after handling, remove contaminated clothing and wash before reuse, avoid eating or drinking near working area

Toxicological Information

Routes of Exposure: Skin, eye, ingestion, inhalation
Acute Toxicity: Ingestion harmful; irritation to eyes, skin, respiratory system
Chronic Toxicity: Carcinogenic to humans (IARC Group 1), chronic inhalation increases cancer risk, can provoke allergies, asthma
Symptoms: Rash, asthma, cough, breathing difficulty, eye and skin irritation
Sensitization: Known to cause allergic response on skin
Carcinogenicity: Classified carcinogen by IARC, NTP, ACGIH
Other Effects: Risks of kidney and lung damage after prolonged exposure

Ecological Information

Aquatic Toxicity: Highly toxic to fish and aquatic organisms, persistent in sediments
Bioaccumulation: Nickel ions can accumulate in aquatic and terrestrial organisms
Mobility in Soil: Nickel sulfate is water-soluble, may migrate through soil to impact groundwater
Persistence and Degradability: Not biodegradable; nickel ions remain in environment
Other Adverse Effects: Toxic at low concentrations to aquatic plants, long-term environmental threat in case of uncontrolled spills

Disposal Considerations

Disposal Methods: Collect in secure containers, handle as hazardous waste in compliance with local, state, and national regulations. Chemical must not be dumped in drains, sewers, or surface waters
Contaminated Packaging: Decontaminate containers if possible before disposal, otherwise treat as hazardous waste
Special Precautions: Consult authorities or certified waste handlers to ensure safe and legal waste treatment. Track disposal records for future reference.
